Application filed January 31, 1917. Serial No. 145,786.

To (/76 whom it may concern:

Be it known that I, Howano M. DUDLEY, a citizen of the United States, and a resi dent of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Dyeing-ll'lachines, of which the billowing is a specification.

ltiiy invention relates to a dyeing machine and refers particularly to a machine adapted, for the dyeing of textile libers compri id within a dyeing chamber, the dyeing being accomplished by the forced passage of the dye liquor through the fiber mass.

Among the objects 01' my invention is a dyeing machine particularly suitable for the dyeing oi warps in the ball, whereby the condition of the fiber may be accurately and readily judged at any stage 01" the treatment without opening the dyeing chamber and whereby even results may be obtained without disturbing the fiber to be dyed.

Another object of my invention is a dyeing machine in which the dyed goods may be alter-treated with water, steam, air or other materials or substances without handling the dyed goods.

llther objects of my invention will. be evident upon a consideration of my specification and claims.

it have tound that the even or uneven dyeing results obtained in a machine of this general character depend largely upon the particular shape of the openings through which the dye liquor enters the liber mass, and that unevenness can be prevented by the use of openings oi a particular shape, the conformation of which enables the liquor to spread itself through the fiber mass without; the formation of channels of tiow.

i have further found that this desirable result can be obtained it the fiber-mass is supported in the dyeing chamber upon sevcral. series of upwardly converging elements, as cones or pyramids, arranged along longitudinally disposed. openings.

la the use of many dyestuli's it is neces sary, altcr dyeing to treat the dyed goods with water for washing purposes, or with solutions of chemicals such as metallic salts or oxidizing products, for the purpose of ait'teitreatment, or with oxygen or air for oxidizing or drying purposes. In the following oi these after-treatments it is essential that every portion of the dyed goods be tl'ioroughly and uniformly treated and that. the operation be performed as readily and quickly as possible. All 01' these results are obtainable by the use of the device of my invention, in which the goods are placed in the dyeing chamber and then rapidly, easily and completely dyed and atter-treated without further handling of the goods and without the formation of channels by the liquids employed. The device therefore insures even and uniform results with a minimum oi time, labor, and expense.

One form of my device is shown in the accompanying drawings in which similar parts are designated bv similar numerals.

The outer portion of the dyeing machine, as illustrated, comprises the upwardly converging cover 12 removably attached to the annular member 13 by the screw bolts 14-, let, the member 13 being movably attached to the shell 15 by means of the screw bolts 16. 16, the shell 15 being attached to the shell 17 by the bolts 18. 18, the shell 17 being attached to the downwardly converging shell 19 by the bolts 20, 20, the shell 19 being attached to the centrifugal pump 21 by the bolts 22, 22. The pipe 23 connects the chamleer ot' the pump 21 with the three-way pipe 24, the latter having the pipes 25, and 27 'tted respectivelywith the valves 28, 1 2 and 30. The pipe :25 is connected with an air compressor, not shown; the pipe 26 opens into the air and the pipe 27 may be connected with a drain or receptacle as desired. The pump 21 is connected with the pipe 31, which in turn connected with the pipe the latter being connected with the pipe carrying the valve 341, the pipe 35 carrying the valve 36 and the pipe 37 carrying the valve 38. The pipe 33 connected with a dyeedissolving tank, not shown, the pipe is connected with a liquor-reserve tank 39, andthe pipe 37 is cimnected with a water supply.

The object oi? the reserve tank 39 is to 1 "therein, its vertical movement being-1 governed by means of the screw-bolts 16, 16 which thread in the projections 41, ll of the shell 15.

The pipe 12 connects the upper portion of the interior of the shell 15 with the liquor reserve tank 39 and carries the valve t3. The pipe 14:, carrying the valve 15 may be connected with a drain, not shown.

A fixed fiber-stun ortinn plate id is situated between the shells 15 and 17 and coinprises a series otparallel grate-bars 47, 47, the bars oi which carry upwardlv and down-- wardly inclined cones 1-8, 18, allowing the openings 19 between the grate-bars.

The device is provided with a movaole annular foraniinous plate 50, the construction of which is similar to the foraminous plate 46.

In order to facilitate reteronce to the various chambers, they will hereafter be referred to as the top chamber 51, the dyeing chamber 52, the liquor-supply chamber 53, and the lower chamber 5%.

A sample dyeing machine 5. 3 exactly simi lar to the one above descriliied except that it is in smaller proportion and c: rries the threaded closed top 56 instead of the top 12. is connected to the liquonsupply chamber by the pipe 57 carrying the valve 58. The upperportion of the sample machine is connected with a pipe 59, capable of being revolved into the position shown by the dotted line 60.

A pipe 61 connects the thermometer 62 with theliquor-supply chamber the pipe is or annular innate-c 61 being extended beyond the thermometer into the pipe (53, capable of being revolved into the position shown by the dotted line or.

perforated steam pipe 65 is within the liquor supply clnnnber The top chamber 51 contains a number of series oi upwardly conv rging cones 66, (it; supported by the diamond-shaped bars 67, 57. Series of similarly shaped downwardly converging cones 68, 68, supported by the members 69, 69, are situated within the lower chamber 5 1-.

The operation oithe device is as follows: 1

The top 12, the annular member 13 and theiim'aminousplate 50 are removed, and the goods to be dyed introduced into the dyeing chamber upon the toraminous plate in. The ioraminous plate 50-is then placed upon the: goods, and the annular member 13 introduced and moved downwardly by means of the screw bolts 16, 16 threaded in the projectingmembers all, 41, the annular member 13 pressing upon the :l'oraminous plate 50. This downward movement of the annular member 13 and the tor-aminous plate 50 is continued until the proper pressure has been obtained upon the goods in the eyeing chamber 52. Goods are similarly placed in the sample device l alves =15, 28, 29, 30, 38 and 8% are closed and valves 58, 13, and 36 are opened,

and the pipes 59 and 63 situated as shown by the dotted lines 60 and 6d. sary dyestuli' having been dissolved in the dye dissolving tank, not shown, connected with the pipe 38, the valve 8% is opened and the centrifugalpump 21. started. pump 21 forces the dye liquorupwardly between the cones 68, 68 in the bottom chamber 54-, the liquor supply chamber 53, the toraminous plate -16, the dyeing chamber 52 and the goods contained therein. As the liquor rises it will pass through the over- The neces- The t tlow pipe :12 into the liquor-reserve tank 39,

from which it will pass through the pipe 85 into the pump 21, thus allowing of a continuouscirculation of the dye-liquor upwardly through the deviceo During this operation the dye-liquor is forced upwardly through the sample device 55 and the goods contained therein. The temperature is varied by means of steam introduced through the steam-pipe 65 and the temperature determined by means of the thermometer 62. From time to time, the valve 58 is closed, the top 56 of the sample device 55 removed and the goods contained therein examined to determine their condition, and the top 56 replaced and the valve 58 opened and the dyeing operation continued until a test of the goods in the sample device shows them to be properly dyed.

The next step is the removal of the dyeliquor contained in the device. This is acconiplished by closing valves .413, St and 36,

opening valve 30 and stopping the pump 21. This allows all 01' the dye-liquor in the do vice to drain through the pipe 27=into a suitable receptacle for .tuture use if desired.

The next step is that of washing the excess of dye-liquor from the goods and this is aceon'iplishcd by closing valve 30 and o jioning valves and 45, and starting pump This allows fresh water to enter through the pipes 37, and 31 into the pump which forces it upwardly through tho device and the goods contained therein and through the overflow pipe l4; into a drain.

The next step is that of oxidizing the dyeings. ii. oxidizable, by means of air or of drying the goods. This is accomplished by placing the pipes and G3 in the position shown by the full lines, i ilacing the top 12 upon the device, a'liixing it thereto by means of the screw-bolts 1%, ll, and attaching the upper open end 01' the top 12 to a vacuum or suction pump, not shown. The valves .5 and 38 are closed, the valve 29 is opened, and the pump 91 stopped. The vacuinn or suction pump attached to the top 12 thus draws air through the pipe 26 upwardly through the device and the goods contained therein. It the amount of air thus obtained is insullicient :tor the purposes desired, the valve 2 connecting the pipe. with an air compressor may be opened and the valve closed and thus sutlicient air may be obtained. It is evident that the air passing through the pipes 25 and 26 may be heated before its introduction into the device. it desired.

The particular formatimi ot the lioraminous plate 46 causes the dye liquor to be spread out and evenly distributed through the goods causing even dyeings, the plate 50. because oi its similarity to the plate l6. causes a. more regular pressure oi. the dye liquor within the dyeing chamber and the conical members 66. 66 and 8. ($8 intensity this distribut on and regularity oi? pressure.

ll; is to be further noted that the goods are dyed, washed and after-treated or dried without handling. and that all of the operations are under exactly the same conditions and that the condition of the goods being dyed or treated can be determined at any time during the operation without interrupting the operation by examining the goods in the sample. device 55.

in the modification shown in Figs. 7. 8, 9, l0 and 11. the foraminous plates 46 and 50 ot Fig. l. conn'irise a series of parallel :l'rat bars 70. 70. the bars oi which carry upwardly and downwardly inclined pyrainids '51, 71. allowing the openings 72, 72 between the grate-bars, and the top chamber 51 and the bottom chamber 5 contain respectively a number of series of upwardly converging and downwardly converging pyramids 78, 7 3 supported by the diamondshaped bars T l, 74. In this modification it is advisable to have the top 12, the member 13 and the shells 15, 17 and 19, and the pump 21 oi a rectangular shape, the sample device 55 being also rectangular.

In the modification shown in Fig. 12, the top 12 oi Fig. 1 is replaced by the domeshaped top 75, which is attachable to the member ll) by means 01'' the screw-bolts 76, 7 6.
